Should Mr Barron's reported postion be true, here's some words for him to consider from my own personal point of view:
No more AAVAs
No more doing anything for NATS on rostered days off (which includes Operational Conversion Training for his shiny new Prestwick Centre).
No more carrying extra validations. I will be handing back 3 or 4 to bring me to the published Unit Minimum.
No more running single manned sectors where the PSS states there should be 2 controllers.
No more LCE duties, I'll live with dropping pay a little.
None of the above are 'industrial action'. I will merely be complying with the Terms and Conditions of employment which NATS have contracted me to do. And I suspect I will not be the only one doing this.
